HOOD.

To all whom it may concern:

Be it known that I, -BARNE Y BERNARD, a citizen of .the United States, .and residing at Detroit, in the county of Wayne and State of Michigan, have inventedanew and Improved Hood, of which the following is a specification.

The invention has reference to sectional hoods for inclosing the engines of motor vehicles and relates particularly to those portions of the hood in and around the joint, the object being to stiffen the joint and reduce the weight, as well as to provide means whereby such :wateras may leak through the seam is conducted to one end of the hood and discharged free from the engine.

In the ordinary constructions, the pivot rod wherebythe upper sectionsjof the hood are joined extends straight through from one end of the hood to the other, the metal of the sections being looped around it at successive intervals. The axis of the rod is substantially coincident with the upper tangential plane ofthehood (sometimes being below the metal and sometimes above) which tends to cause sagging near the middle, and, in order to overcome this, the meeting edges of the sections have in some cases been reinforced by longitudinally extending bars. This has, of course, added to both Weight and cost. v

The present invention consists in a hood having a pivot rod or bar, the central portion of which is depressed to itself form the lower chord of a girder or truss the compression element of which is made up of a downturned web or flange of one of the sections. In this manner a amaximum strength is secured for a minimum weight of material. The invention further consists in a construction of the nature stated wherein the downturned flange of the section together with the depressed portion of the rod form a longitudinally extending trough in which water which leaks through the joint is conducted beyond the engine and discharged. The invention also consists in a hood wherein the downturned flange of one section is wrapped around the pivot rod and forms therewith a longitudinally extending trough, and wherein a cooperating flange of the opposite section terminates close to the trough to direct such water as may leak through the seam thereto. The in ention further consists i the Specification of Letters Patent.

details of construction shown, described and claimed.

In the drawings, Figure 1 is a perspective view looking from front to rear showing a preferred embodiment of the invention. Fig. 2 is an enlarged fragmentary plan view of the parts at one end of the joint. Fig. 3 is a sectionon the line 33 of F 2. Figs. 4 and 5 are sections on the lines 4& and 55 of Fig. 3.

As is usual, the hood preferably includes top sections 1 and 2 and side sections v3 pivoted thereto. nected'by pivot means, one element of which is a .pivot rod that comprises acentral portion 4 extending almost from one end of the hood to the other and lying well below the horizontal plane which is tangent tothe hood at the joint. Besides the part 4, the rod includes the alined endportions or piv- The sections 1 and 2 arecone ots. 5 that are joined to the former by the upstanding portions '6. The pivots are preferably above the horizontal tangential plane previously referred to, as best indicated in 3. Between the portions6 of the rod, the section 1 is bent downwardly to forma web or flange8,the lower edge of which is wrapped around the part; 4 and preferably welded thereto so that the rod and web together form a girder .or truss with the rodin the zone of tension. It is also preferred to make theiangle between the web 8 and the adjacent portionof the section 1 acute. The metal of the sections land 2 ;is cut away-as indicatedat9 (Fig. 2) to allow clearance.

The elements which cooperate withand form complementary pivot members for the parts 5 are preferably metal loops 10 spot welded together and to the lower side of the section 2. The metal of the section 2 is turned down for a distance equal to the length of the web 8 to form a flange 11 which bears against the web when the hood is closed to form a close joint therewith (Fig. 4). It will be observed that the rear end of the hood is higher than the front end (Fig. 1), consequently any water leaking through the joint and collecting in the trough formed between the rod and the web 8 is conducted to the front end, where it overflows beyond the engine as will be readily understood.

The construction is inexpensive, both in material and in the steps of manufacture. When in position on the car the upper surface is smooth and unbroken, thus conforming well to the lines of the latter. The actual details of construction may, of course, be varied considerably without departing from the spirit of the invention.

I claim V 1. In a hood, the combination of two sections one of which has a downturned edge portion forming a web, a pivot rod having a depressed central portion extending longitudinally of the lower edge of the web and spaced from the upper portion of the web for the greater part of the length thereof, said rod also having alined end portions located at a higher level, and means carried by the other section cooperating with said end portions to form a pivotal connection between said sections.

2. A hood comprising a section having a downturned edge forming a web, a reinforcing member secured to and extending longitudinally along the extreme lower portion 7 of said web and being spaced from the upper portion of the web along the mid-portion of the length thereof, said member rising near the ends of the web and forming alined pivot elements, a second hood section, and means carried thereby and cooperating with said pivot elements whereby a pivotal connection between said sections is formed.

3. A hood comprising two pivotally con nected sections having meeting edges, one of the edges comprising a downturned web and a longitudinally extending reinforcing element therefor, said element and said web together forming a longitudinally extending trough in which water that may leak through the joint between the sections is received.

4. In a hood, the combination of two pivotally connected sections having meeting edges, one of the edges comprising a flange downturned from the corresponding section, the other edge comprising a web downturned from the other section and having its lower margin bent laterally under the margin of the flange.

5. A hood comprising two pivotally connected sections one of which has a downwardly extending web terminating a short distance from each end of the section, a pivot rod having a depressed central portion extending along the lower margin of said web and spaced considerably from the upper portion of the web throughout the greater part of the length thereof, said rod having alined end portions located at a higher level, and means fixed to the other section and cooperating with said end portions for forming a pivotal connection between the sections.

6. A hood comprising two sheet metal sections one of which includes a down turned web at its edge and a longitudinal extending reinforcing bar fastened to the lower edge portion of the web, said reinforcingbar being substantially U-shaped in longitudinal cross-section below the upper edge of the web.

7. A hood comprising two sections one of which includes a down-turned web at its edge and a longitudinally extending reinforcing bar located along the lower margin of said web and secured thereto, said bar also having alined end portions lo cated at a higher level, and a pair of loops secured to theother section and cooperating with the end portions to form a pivotal connection.

8. A hood comprising two sections notched at the ends of the meeting edges, one of the sections having a downwardly turned flange between the notches, and a combined pivot rod and reinforcing bar having a depressed central portion located below the longitudinal central line of the web and fixed to the lower margin thereof to form a girder, the ends of said bar extendin upwardly through the notches and being a ined with one another, and loops secured to the lower side of the other section and cooperating with the ends of the bars to form pivotal connection.
